This is what I gleamed from putting together the above sources.
It seems from these articles that cancer uses a cell division
technique that can be interrupted with a build up of lactic acid.
Lactic acid is more easily cleared up or removed which high sugar, or
carbohydrate diets. ( seems like it’s good for runners, but not good
for cancer patients. )

It seems like cancer growth is at it’s worst when Lactic acid has not
built up in a while to inhibit/ reset the rogue energy cycle that
forms.

Lactic acid builds up in muscles that are being used, but is
transported through blood flow to the rest of the body.
Blood flow during intense exercise is restricted to non-vital organs,
which would make it hard for lactic acid to reach those organs.
Prolonging Lactic acid in the body might help fight cancer.

From what I have read, this seems to indicated that intense exercise (
causing a warmness or burning in your muscles ) and not carb-loading
before a workout, or immediately afterwards is an ideal strategy. It
may be that the rise in cancer in our society might be related to the
sharp decline in intense exercise.

End of story, no pain no gain, when it comes to exercise.
It looks like they are looking for a pill to replace the simple need
for us to work physically harder in our daily lives.
